Python – Pip Install – Proxy Error – 'Cannot connect to proxy.', OSError'
Question:
I want to install some modules in a Enterprise VM in order to create some Python Scripts. I’m trying to use PIP with Proxy to do it. I’m using this command lines:
C:Usersuser>SET HTTPS_PROXY=https://user:[email protected]:8080
C:Usersuser>SET PROXY=http://user:[email protected]:8080
C:Usersuser>pip install datetime
To have access to my virtual machine I’ve this credentials:
- USER: NAN/user
- PASS: pass
But I am getting this error:
Collecting datetime

What I need to do in order to get the python module?
Answers:
Try like this:
set HTTP_PROXY=http://199.00.11.11:8080
set HTTPS_PROXY=https://199.00.11.11:8080
First, install a proxy authentication service like CNTLM)
Second,
set http_proxy=http://username:password@proxyAddress:port
set https_proxy=https://username:password@proxyAddress:port
I also faced this issue even with proxy, adding "–isolated" helped
For eg: pip install datetime –isolated
Note: My proxy is already set in "pip config"
I recently had a similar issue doing pip3 install awscli on my local mac. I checked my env and there were no proxies set there. The solution that worked for me was disabling proxies from the network which got set on my machine for some reason. To do that
- Click on Wifi
- Open Network Preferences
- Click Advanced button
- Go to proxies tab
- Uncheck Web Proxy and Secure Web Proxy
Again, I know that network proxy misconfiguration is rare and this answer may not be the most suitable answer. But this might come in useful for some folks as this is right now the first link that comes on google search for pip install ProxyError.
If your proxy configration is OK,
It may be because your pip version is too high.
Try to lower your pip version
python -m pip install pip==19.3.1
Then restart your terminal.
You can try this method to see if it works
In my case, it was only because the 【VPN】 software modified the 【System Proxy】 configuration of the 【IE】 browser.
I modified it back in this way:
- open 【IE】
- Press 【Alt+X】 and scroll down to 【Internet options】
- Click on the 【Connections】 tab
- Press the 【LAN settings】 button
- Uncheck the 【Proxy Server】
This is how my problem was successfully solved.
This works on Windows 10 for me:
-
Search for Proxy Settings in Windows Start Search, open it
-
Under Manual Proxy Setup, uncheck "Use a proxy server".
Alternatively, you may just add exceptions for the sources you want to install packages from.
Try like: Go to *control panel –> Internet options –> Connections –>LAN Settings ->mark ‘use proxy server for local address’ options.
I ran into the same problem and the solution in my case was to unset the HTTPS_PROXY variable, because my proxy does not accept https requests.
I found the solution in this page : https://urllib3.readthedocs.io/en/1.26.x/advanced-usage.html#https-proxy-error-http-proxy
All proxy variables are set by the os admin :
HTTP_PROXY=http://my_domain:8888
NO_PROXY=*.internal_domain,172.*,
HTTPS_PROXY=http://my_domain:8888
To update pip for example, I have to run :
unset HTTPS_PROXY ; pip install -U pip
Use the following code
pip install --trusted-host pypi.org --trusted-host files.pythonhosted.org datetime
You can change datetime with the name of any package you want.
